MEANS FOR TRANSPORTING LOADS.

{SPEGIFICATION forming part of Letters Patent No. 425,724, dated April 15, 1890.

Application filed March 26, 1888. Serial No. 268,526. (No model.) Patented in France November 5, 1887,1l0. 136,773; in England December 21, 1887,110. 17,573; in Belgium February Z9,1888,N0. 80,816, and in Spain April 10, 1888, No. 7.506.

186,773, dated November 5,1887, and for which they have jointly obtained a patent in Spain, No. 7,506, dated April 10, 1888; a patent of Great Britain, No. 17,573, dated December 21, 1887, and a brevet in Belgium, No. 80,816, dated February 29,1888) of which the following is a specification, reference being had to the accompanying drawings.

Our invention relates to means employed for transporting a load from one point to another across a water-course or ravine, or where the conditions are not favorable for making a road, or where it is impossible or difficult to build an ordinary bridge.

In carrying out our invention we employ a girder or light bridge-like structure supported on piers,towers, or other elevated supports at a sufficient height-say high enough for the highest vessel to pass underand provided with rails or ways, upon which runs a frame-work mounted on rollers, to which are attached metal rods or cables for suspending a platform or car, which may be, for example, at the height of the banks or quays of a river or water-course, and within which or on which are carried the passengers, railwaycars, or other vehicles, animals, or other merchandise which it is desired to transport across the river, water-course, ravine, or space which is spanned by the girder.

Our improvement consists in certain means, hereinafter described and claimed, of supporting the said framework on the rails or ways, and of suspending the platform or car from said frame-work, and in certain means, hereinafter described and claimed, for producing the movement of the said frame-work and suspending the platform or car upon the said rails or ways.

In the accompanying drawings, Figure 1 represents an elevation of a bridge of the suspension type furnished with a transporting apparatus according to our invention. Fig. 2 represents a side elevation, 011 a larger scale, of a portion of one of the girders of the bridge, a rail supported thereon, a set of wheels or rollers running on said rail, a portion of a frame suspended from said wheels or rollers, and a portion of one of the suspension rods or cables by which the car or platform is to be suspended from said frame. Fig. 3 representsa transverse section of a portion of the bridge corresponding with Fig. 2. Fig. 4 shows a side elevation of a portion of a bridge'girder on a smaller scale than Figs. 2

and 3, with two adjacent sets of wheels or rollers-such as are shown in Figs. 2 and 3- running thereon. Fig. 5 is aplan corresponding with Fig. 4. Fig. 6 represents in section va portion of the floor of the suspended platform or car and a portion of the propelling apparatus and a motor therefor on a larger scale than Fig. 1.

Similar letters of reference designate corresponding parts in all the figures.

Referring to Fig. 1, the bridge therein represented is a suspension-bridge of the ordinary type, but so constructed that it only contains parts necessary for the support and travel of the carry in g-frame and car suspended therefrom. No flooringis necessary. There is only a narrow gangway .2, Fig. 4;, for the passage of the man whose duty it is to grease and keep the rolling part of the apparatus in order. The bridge-platform consists only of two beams a, Fi 3, held together by crossties b and furnished at their lower parts with angle-irons 0, upon which are su-pportedrails d, which serve as the track for the flanged wheels 6. These wheels are united in pairs by axles f, and two of these pairs of wheels are brought together in such manner as to constitute a train of four wheels, as may be seen by reference to and comparison of Figs. 4 and 5.

Each of the axles f of a train has suspended on it a stirrup g, Figs. 2 and There are then two of these stirrups for a train of four wheels, and they carry at their lower ends pins h, over each of which are passed two other stirrups '6, to which the branches are bolted, as shown in Figs. 2 and 3, through the longitudinal piece j of the traveling frame, which is shown in Figs. 4 and 5. This frame is thus suspended from the difierent trains of wheels by the system of stirrups g t', the number of the trains of wheels necessary to sustain it depending upon its dimensions and upon the weight which it itself has to carry. In the drawings, Fig. 1, itis supposed that there are seven trains of wheels on each side, fourteen in all. The frame is composed of the longitudinal bars j, secured together by cross-ties 7a, which will be hereinafter further described, and by diagonal braces I, Fig. 5. Itis from this rolling frame that the transporting-oar m is suspended, as shown in Fig. 1, by means of rods or metallic cables n, conveniently attached in triangular form. These suspension rods or cables are attached to stirrups o, riding on the longitudinal bars j of the rolling frame and resting on saddles p, bolted upon the said. bars, Fig. 2.

We will now describe how the movement is given to the transporting car or platform m and the rolling frame j lo Z,- from which it is suspended, with reference to Figs. 1 and 6. Across the river or water-course therein represented there is laid from one bank to the other a cable or chain 19', the ends of which are firmly secured to the shore. This chain or cable is long enough to lie upon the bottom of the river with considerable slack. This cable or chain passes under the car or platform m over a chain wheel or pulley q, the shaft or axle q* of which is supported in bearin gs fixed under the car orplatform, and the said chain wheel or pulley has rotary motion given to it in either direction from a reversible motor m, placed upon the fioor of the car or platform m. This motor may be of any convenient or suitable kind-as, forinstance, a steamengine or an electric motor. The main shaft 1' of this motor is represented in Fig. 6 as geared by spur-gears 7" q with the shaft 11* of the pulley q. In passing over the pulley or wheel q the chain is lifted from the bottom to plunge again into the Water as soon as it passes, thus leaving the navigable channel completely free. This means of propelling the car or platform will prevent any oscillation of the suspended car or platform by taking hold upon the bottom of the river or watercourse. Moreover, this method of propelling or giving motion to the car or platform insures it always arriving at the desired landing-place, and being there securely held during the embarkation and disembarkation.

What we claim as our invention, and desire to secure by Letters Patent, is

1. The combination of the frame j 7c 1, the wheels 6 and their axles, the stirrups g, suspended on the axles, the pins h, provided in said stirrups g, and the stirrups i, suspended on said pins and supporting the said frame, the said stirrups g and 11 forming a double articulation between the wheels and the frame, as herein set forth.

2. The combination,with a girder or bridge span provided with tracks and supports therefor, of the rolling frame running on said tracks, a car or platform suspended from said rolling frame, a motor on said car or platform, and a chain or cable secured at its ends and passing over a pulley or chain wheel driven by said motor, substantially as and for the purpose herein set forth.

In testimony whereof we have signed this specification in the presence of two subscribing witnesses.
